Speciflcation' of Letters Patent.

Patented Jan. 25, 1910.

Application flled .Tune 12, 1908. Serial No. 488,056. I

To all whom lit may concern:

Be it known that I, WALTER T; GoDDAnD', of Victor, in the county ofOntario and State of New York, have invented certain new and usefulImprovements in Insulators; and I do hereby declare the following to bea full, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe referencenumerals marked thereon.

The present invention relates to iusulators for high voltagetransmission lines and it has for an object to provide a construction inwhich the line wire is removed as far as possible from the pin orsupport without unduly increasing the weight of the insulator.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a view of a support having an insulatorthereon embodying this invention; Fig. 2 is a View partly in verticalsection showing one of the insulators; and Fig. 3 is a sectional viewshowing the manner cf Securing the conductor to the insulator.

In the embodiment of the invention herein shown, the insulator issupported horizontally, the support 1 in this instance being in the formof a cross piece secured to a `post 2. The insulator preferablycomprises a plurality of sections, three of Which, 3, 4, and are, inthis instance, flared and fitted one within another and are closed attheir smaller ends, which abut. The sections 3, 4 and 5 are securedtogether in any suitable manner but preferably by screw threads 6cemented together, the inner section 3 being secured to the support 1and having its inner end arranged within the section 4,` the outersection 5 having a greater flare than the section 4, and the section 4having a greater flare than section 3.

carried by the insulator is a conductorsupporting section in the form ofa vertically disposed flange or ring 7 which .has

such a diameter that Vthe conductor is removed from the support 1 adistance to reduce the static strain to a minimum. This ring preferablyhas a grooveddperiphery to which the conductor 8 is secure in any suit-'conductor rests in the groove of ring able manner. In the presentinstance th is secured to the insulator by two tie wires 10 and 11looped around the ring on opposite sides of the latter and sectlred attheir ends to the conductor as by split clamps 12. This arrangement doesnot produce on the insulator any twisting strain that would tend toseparate the parts of the insulator.

In order to prevent an arc formed between the insulator and its supportdestroying or Cracking the insulator, I provide two arcing members 16and 17, one connected to the support, the other connected to theinsulator and both preferably projecting up- Wardly to a plane above theinsulator. Preferably, one of the members 17 carries a clamp 13 which issecured to the conductor 8 and tie' wires 10 and 11 so as to bein directconnection with the conductor, while the other member is clamped to thesupport 1 and has an extension 18 which projects in proximity to theflared portion of one of the petticoat sections.

The construction and the arrangement of the arcing member are notclaimed in this application, but form the subject matter of a divisionalapplication filed by me on October th, 1909, Serial No. 524,469, forimprovements in insulator protectors.

In this construction of insulator, the flared ends of the sections forma number of circular lvertically disposed arcing barriers between thesupporting ring 7 and the support. All parts of the insulator areexposed to the atmosphere but this is not material as all insulators7tests are made under this assumption that at one time or another theinsulator will be required to carry its full capacity while covered witha film of water. Further, the flaredbportions of the sections beingarranged horizontally cause the insulator to drain quickly.

I claim as my invention:

1. The combination with a horizontally arranged support, of an insulatorcomposed of a series of horizontally arranged flaring sections havingclosed4 outer ends secured to the support, and a ring shaped insulatingmember surrounding the flared sections and having means for securing anelectrical *conductor to the periphery thereof.

, 2. The combination with a horizontally arranged support, of aninsulator section closed at its outer end, fitted over the support andhavin a vertically disposed aro barrier surroun mg the support, and aring-- shaped conductor-suIporting member surrounding the section etweenthe 4`closed end and the barrier, and having means for seone withinanother, and a ringflshaped insulating member secured to the outersection and having a ooved perihery.

4. The com ination wit a horizontally arranged support, of an insulatorsection closed at its outer end, fitted over the sup- .gort and having.a vertically disposed aro arri er surroun mg the support, and aringshaped conductor-su portmg member surrounding the section tween theVclosed end and the barrier and having a grooved periphery.
